Bubble Sort in c

Bubble Sort in c

Bubble Sort is probably one of the oldest, most easiest, straight-forward, inefficient sorting algorithms. It is the algorithm introduced as a sorting routine in most introductory courses on Algorithms. Bubble Sort works by comparing each element of the list with the element next to it and swapping them if required. With each pass, the largest of the list is “bubbled” to the end of the list whereas the smaller values sink to the bottom. It is similar to selection sort although not as straight forward. Instead of “selecting” maximum values, they are bubbled to a part of the list.

PROGRAM:

/*C Program To Sort data in ascending order using bubble sort.*/#include<stdio.h>int main(){int data[100],i,n,step,temp;
printf("Enter the number of elements to be sorted: ");
scanf("%d",&n);for(i=0;i<n;++i){
printf("%d. Enter element: ",i+1);
scanf("%d",&data[i]);}for(step=0;step<n-1;++step)for(i=0;i<n-step-1;++i){if(data[i]>data[i+1])/* To sort in descending order, change > to < in this line. */{
temp=data[i];
data[i]=data[i+1];
data[i+1]=temp;}}
printf("In ascending order: ");for(i=0;i<n;++i)
printf("%d ",data[i]);return0;}
